Answer:
Centrosomes are the organelles present in the animal cells which are made up of two types of centrioles, a ring structure made of microtubules.
The centrosomes are present outside the nucleus in the cytoplasm which after nuclear envelope disappearance play their role in cell division.
The centrosomes play an important role during the cell division as they help organise the microtubules to form spindle fibres. The mitotic spindles help separate the sister chromatids during the mitotic phase.
Thus, centrosomes play an important role during mitosis.
Stanley Miller is the scientist that is credited with the idea that
early life formed through a successions of chemical reactions that make simple
compounds more complex. He made a breakthrough of experiments in the origin of
life by representing that a wide range of vital organic compounds can be produced
by fairly simple chemical processes from inorganic substances. Although he
worked with Urey on this experiment, Miller is far more well-known and credited
for the discovery.
The tragedy of commons was an example of overexploitation and was:

The process that is responsible for causing menstruation is called menstrual cycle. Menstrual cycle is the natural change that occurs specifically in the ovaries and uterus or in the female reproductive system that gives possibility to pregnancy. This process is required for the ovocytes to be produced, and also for the uterus to be prepared for pregnancy.
